PF Filter Diaphragms

A filter’s diaphragm is responsible for moving water in slurry through the filter media by either compressed air or pressurized water.

The diaphragm is essential in transferring the pressure to the slurry for effective dewatering, where most water not adsorbed on the solid particle surface is drained from the plate chamber.

Diaphragms are made from polymers that operate under continuous strain and stress due to the stretching and contraction after every filtration cycle. Diaphragms, therefore, are consumable parts that require frequent replacement.

The frequency of replacement is dependent on process-specific conditions and will vary between different customer applications.

Diaphragms need to follow strict quality controls in both dimensions and materials of construction, to ensure reliable and optimal lifetime that minimize unexpected diaphragm failures (such as leaks affecting cake moisture quality) and costly unplanned shutdowns for diaphragm replacements that impact production.

Benefits:

• Extended lifetime
• Increased reliability
• Decreased leakages
• Robust

Applications:

Suitable for all mining and metals applications, as well as Chemical Process Industries.

For special applications, a range of materials other than NR can be used to ensure robustness against other pH ranges and chemicals.
